Hello, I brought a HTC HD7S unlocked version from Amazon. When I first got the phone, I put a AT&T prepaid sim card into the phone, it works well. However, because I need to modify the Live ID, I reset the phone to the factory setting. And then, bad things happened. When I put a AT&T prepaid sim card, it said, the SIM card is missing or invalid. When I put another AT&T prepaid sim card, it still did not work. However, when I put a AT&T family plan card into my phone, it works well. So what`s the problem and how can I use a AT&T prepaid sim instead of the family plan sim card ??
Best wishes for everyone
Help anyone who knows the answer . Thank you so much
Need a replacement phone since mine crapped out and not up for form VZW. Found an unlocked phone that I like and would allow me to upgrade to LTE. The phone doesn't have a SIM card but I assume I can get one from VZW and/or Amazon. Is anything needed to get an unlocked phone onto VZW network?
Hi Everyone
Heres a neat problem somebody may be able to shed some light on.
I have a samsung galaxy s2 hd lte I757M , it just expired off of contract from bell.
I wanted to unlock it and was ready to when I decided to check if the phone was locked by using *#7465625# and it says that everything is OFF so that means its unlocked, from what I have been reading.
I bought a sim card from roam mobility and booted it up. It did not ask for any code for unlock. It only says "No Sim card Emergency calls only. I installed it properly exactly the same way as the original one came out. Its clean to.
(Keep in mind I bought this phone brand new from bell never serviced or rooted)
I spoke to roammobility and they say the phone is supported on their network.
I thought the sim maybe defective so I tried it in a locked samsung galaxy s2 i9100m and right away when booting it asked for a unlock code, so to me it sees the sim is there. . I also tried it in a locked moto g with the same results..
Can anyone tell me why my phone does not read the sim or see it? Could this be some other type of lock?
Hi everyone
I’m kinda puzzled with this note 8 and need some advice. Recently got a note 8 from AT&T and since I was traveling I had it unlocked to use by a third party company ( since att doesn’t unlock until Device payment is complete)
I got the code, unlocked the phone successfully. Before I left USA I put a working T-Mobile sim to test if connectivity, no luck, it doesn’t work, I tried a Verizon sim, nothing works....
Note... this T-Mobile sim and Verizon sim if I put it on a different device it will work...
any reason why this is happening

The phone is not unlocked. Seems like an error happened when you got the unlock code. I'd try again.
Did you use this device on the att network? I mean, do you have it activated?
If you unlocked it by codes and the message after inserting the code is something like "unlock successfull" then your device must accept other GSM SIM cards.
Also, I would recommend you place a 5 min call with your device, with the att sim card and then insert again the tmob card.
What is the message when you insert the tmobile card in this device?
I did the same thing by using a Tmobile SIM during the unlocking process, and it worked on TMobile right after I unlocked it. It sounded like you did not unlock it using a different network SIM but using some other method. I am not sure if that mattered or not.
I then traveled to Asia, and I bought and used a local SIM card with zero issues. The 4G LTE was faster in that country than AT&T... LOL
How unlock used Samsung Galaxy Book 2 (Verizon) so I can use T-Mobile SIM??
My friend bought a used Galaxy Book 2, put in his t-Mobile Sim and message came up that stated something to the effect that his device needs a Verizon Sim. Even with this message (as someone said it still worked) it did not get a signal.
He cannot return this as he bought it from some 3rd party he will never see again.
He has T-Mobile as a carrier for quite a few phones and has some sort of lifetime extra device -T-Mobile sim plan he can use so he does not want to move just this device to Verizon.
The question is can this be unlocked by Verizon store? And even if it is and APN settings are changed would it work with a T-Mobile Sim?
I know nothing about these LTE laptops and not sure at least for Samsung if the radio in it is somewhat universal or compatible with most US carriers.
Thank you for any advice.
I appreciate it.
Sincerely
Peter
